The comparing of normal circumstances and El Nino circumstances in the Pacific Ocean were presented in the two diagrams. It is important to note that there are different effects from both of the situations.
In the normal condition, the cloud blow and rain to the land because the west pacific wind breeze slow and the east pacific wind breeze really strong. It is good for land life and sea life. In the land, a living thing finds so much water from a cloud. In the sea, there is no domination from the warm water, so that the sea has a cool water and contain rich nutrient for sea life.
Different with a normal condition, because of El Nino, the west pacific wind move totally strong and the east pacific is slow so that the cloud blow to the sea and the warm water flow to eastwards. It can cause the land getting dry. The cool water will be in the deep sea, so the sea has the lack of nutrients.
